Embodiment 1

[0027] Make a glazed effect on a flat plate. Mold a flat plate with china clay and dry. Apply a layer of red glossy bottom glaze on the flat body by dipping glaze, with a thickness of 0.2-0.3 mm; then spray a layer of 0.3-0.4 mm on the bottom glaze by spraying glaze mm white matt glaze. After entering the kiln and firing at a high temperature, a three-dimensional white glaze and a red flat plate are obtained.

[0028] The base glaze is composed of base glaze and colorant, the weight percentage of which is: base glaze 80%, colorant 20%, and colorant is commercial pigment for ceramics or iron red powder for industrial use.

[0029] The base glaze of the bottom glaze mainly includes SiO 2 、Al 2 o 3 , CaO, ZnO, Li 2 O, MgO, K 2 O and Na 2 O, made of any combination of feldspar, quartz, calcite, talc (fired) and lithium china stone, to ensure that the chemical composition of the base glaze of the bottom glaze is as follows:

[0030] SiO 2 : 66% Al 2 o 3 : 12% CaO: 6.3% ...

Embodiment 2

[0040] Make a glazed glaze effect on the daily cup. Mold a cup out of china clay and dry. Apply a layer of black glossy bottom glaze on the cup body by glaze brushing, with a thickness of 0.2-0.3 mm; then spray a layer of 0.3-0.4 mm on the bottom glaze on the cup body by spraying Green glossy glaze. After entering the kiln and firing at a high temperature once, a three-dimensional green glazed black light cup is obtained.

[0041] The base glaze is composed of base glaze and toner, the weight percentage of which is: base glaze 90%, colorant 10%, and the colorant is commercial pigment for ceramics or black powder for industry.

[0042] The base glaze of the bottom glaze mainly includes SiO 2 、Al 2 o 3 , CaO, ZnO, Li 2 O, MgO, K 2 O and Na 2 O, made of any combination of feldspar, quartz, calcite, talc (fired) and lithium china stone, to ensure that the chemical composition of the base glaze of the bottom glaze is as follows:

[0043] SiO 2 : 66.5% Al 2 o 3 : 11.5% C...

Abstract

The invention discloses a method for making ceramic consecrated glaze and its glaze material, which adopts a secondary glaze method in which a bottom glaze is first applied to a ceramic body, and then a top glaze is applied, and the surface tension of the top glaze is far greater than that of the bottom glaze; The ceramic body that has been glazed twice is sent into the kiln and fired at a conventional high temperature. Under high temperature conditions, due to the difference in tension between the bottom glaze and the top glaze, the top glaze cracks to reveal a glossy bottom glaze and a matte surface. The glaze is set against each other to form a consecration effect. The glaze is divided into bottom glaze and top glaze. The bottom glaze and top glaze are composed of base glaze and colorant. The weight percentage of the composition is: base glaze 80-100%, colorant 0-20%, color The agent is a commodity pigment for ceramics or an oxide for industrial use.

Description

Technical field: [0001] The present invention belongs to a kind of post-processing glaze preparation method of ceramics and its glaze, especially to a kind of daily-use ceramics and furnishing ceramic surface ceramic lighting glaze preparation method and its glaze, belonging to inorganic non-metallic ceramic glaze and its The production process is used for ceramic surface decoration to obtain better results. Background technique: [0002] The lighting effect formed on the ceramic surface has a special three-dimensional aesthetic feeling, and its products are very popular in the market. Although bright gold can also be painted on a matte glaze, a second color firing can also achieve a similar consecration effect. However, the process is complicated and expensive, which is greatly restricted in the market, and the durability of the product is not good, the wear resistance is poor, and the color change is not rich. Invention content: [0003] The object of the present inven...
